Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015994, here are decompositions:

3 + 1015991 = 1015994
13 + 1015981 = 1015994
97 + 1015897 = 1015994
103 + 1015891 = 1015994
151 + 1015843 = 1015994
181 + 1015813 = 1015994
241 + 1015753 = 1015994
271 + 1015723 = 1015994

Showing the first eight; more decompositions exist.
